There is a expedition coming up this month to push the Huautla cave system beyond Sump 9 where they stopped the last time. This :http://www.facebook.com/CaveDive, is the link to the Facebook group that will keep us updated on progress throughout the expedition and here: http://www.cdg-exped.org/, is the website for the expedition. I hope everyone will take as big of an interest in this as I have and follow along with these explorers as they make history. :)
